Stephen Hawking: ‘I Held A Party For Time-Travellers… But None Came’

Stephen Hawking recently gave a party – for time travellers.

But while he told plenty of people about the date, sent out invitations and waited patiently for them to arrive, no body came.

Of course that might have been because he waited until the party was over to send out the invites.

Professor Hawking explained his failed experiment in a recent interview with various journalists, written up by Ars Technica.

“I have experimental evidence that time travel is not possible,” he said.

“I gave a party for time-travellers, but I didn’t send out the invitations until after the party. I sat there a long time, but no one came.”

Hawking has previously spoken about the party, which was ‘held’ on 28th June 2009, and produced a video about the experiment – but due to the laws of causality, no one has retrospectively showed up.

Hawking also said that Einstein’s theories offer the possibility of travelling backwards in time – but “it is likely that warping would trigger a bolt of radiation that would destroy the spaceship and maybe the space-time itself”.

In the interview Hawking was also asked about alien life – and reassuringly said that it isn’t likely aliens are coming to visit.

“I’m discounting claims that UFOs contain aliens. Why would they appear only to cranks and weirdos?” he asked. Read the rest of this entry »

Stephen Hawking’s 70th birthday: 17 things you need to know about the physicist

Posted by Ram Kumar Shrestha on January 8, 2012

Happy Birthday to Professor Stephen Hawking, who today celebrates his 70th birthday – nearly fifty years after he was first diagnosed with motor neurone disease.

Here are 17 things you need to know about the most famous theoretical physicist in the world.

1) Born in Oxford on January 8 1942 – 300 years after the death of astronomer Galileo Galilei – Professor Hawking grew up in St Albans, Hertfordshire.

2) After being diagnosed with a rare form of motor neurone disease – amyotrophic lateral sclerosis (ALS) – at the age of 22, Hawking was given just a few years to live.

3) Hawking is as much a celebrity as he is a scientist, having appeared on The Simpsons, Star Trek and having provided narration for a British Telecom commercial that was later sampled on a Pink Floyd album.

4) He had a difficult time at the local public school and was persecuted as a “swot” who was more interested in jazz, classical music and debating than sport and pop. Read the rest of this entry »
